Description

Technical Field

[0001] This application relates to the technical field of heat dissipation of electronic devices, and particularly to a cooling device. Background Art

[0002] In existing cooling devices such as jet cold plates, the cooling working fluid directly flows in the water channels to perform heat exchange for heat dissipation and cooling. As the heat flux density of electronic devices continues to rise, due to impurities and additives in the coolant, when the cooling working fluid circulates in the cold plate for a long time, affected by complex fluid behaviors such as particulate deposition and bubble retention, it is extremely easy to form local blockages in the low-flow velocity areas of the flow channels, resulting in a slowdown in the flow velocity of the coolant, a decrease in the heat dissipation efficiency, deterioration of the heat dissipation performance, overheating of the device, and affecting the safe use of the device. Existing passive anti-blocking strategies mostly rely on filtering devices to filter particulate matter or surface modification technologies to reduce particulate deposition, which have defects such as high maintenance costs and poor process compatibility. Summary of the Invention

[0003] This application provides a cooling device to at least solve the problem of blockage of the cooling flow channel in related technologies.

[0004] This application provides a cooling device, including:

[0005] A device body, in which a medium flow channel is provided, and the device body is provided with a medium inlet and a medium outlet that communicate with both ends of the medium flow channel. The cooling medium enters the medium flow channel from the medium inlet and flows out from the medium outlet. At least part of the device body forms a heat exchange part, and the heat exchange part constitutes a part of the medium flow channel;

[0006] A diversion baffle, rotatably installed on the device body and extending into the medium flow channel. The diversion baffle has at least a first state inclined towards the downstream direction of the cooling medium and a second state inclined towards the upstream direction of the cooling medium.

[0007] Through this application, the cooling medium enters the medium flow channel from the medium inlet and flows out from the medium outlet. The guiding baffle has at least a first state and a second state. When the guiding baffle is in the first state, it can follow the flow direction of the cooling medium, enabling the cooling medium to flow stably, so as to cooperate with the heat exchange part for heat exchange to dissipate heat from the electronic device attached to the cooling device. When the guiding baffle is in the second state, it can reverse the flow direction of the cooling medium. The impact force of the cooling medium on the guiding baffle increases, and turbulence of the cooling medium will increase during flow. Utilizing the directional scouring effect dominated by fluid kinetic energy, it can scour the residues on the inner wall of the medium flow channel, effectively inhibiting particle deposition, forming a self-cleaning dynamic cycle in the medium flow channel, avoiding blockage, ensuring the heat dissipation effect of the device, and providing a system solution with both anti-blocking ability and heat dissipation stability for high heat flux density scenarios.

[0020] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0021] An embodiment of the present application provides a cooling device, including a device body and a flow guiding baffle 20.

[0022] Among them, a medium flow channel is provided inside the device body, and the device body is provided with a medium inlet 101 and a medium outlet 102 that communicate with both ends of the medium flow channel. The cooling medium enters the medium flow channel from the medium inlet 101 and flows out from the medium outlet 102. At least part of the device body forms a heat exchange part, and the heat exchange part constitutes a part of the medium flow channel.

[0023] It can be understood that the heat exchange part is attached to the electronic device that needs to be cooled. When the cooling medium flows through the medium flow channel, it can take away the heat transferred from the electronic device to the heat exchange part, thereby realizing the cooling of the electronic device. Moreover, the cooling medium enters the medium flow channel from the medium inlet 101 and flows out from the medium outlet 102, which can keep the cooling medium in a flowing state in the medium flow channel all the time, and the cooling effect is good.

[0024] In specific implementation, the heat exchange part constitutes a part of the medium flow channel, which can enable the cooling medium to take away the heat on the heat exchange part during the flowing process to achieve cooling and temperature reduction.

[0025] The flow guiding baffle 20 is rotatably installed on the device body and the flow guiding baffle 20 extends into the medium flow channel to guide the flow direction of the cooling medium in the medium flow channel. The flow guiding baffle 20 can rotate relative to the device body so that the flow guiding baffle 20 has at least a first state inclined towards the downstream direction of the cooling medium and a second state inclined towards the upstream direction of the cooling medium.

[0026] In specific implementation, the cooling medium enters the medium flow channel from the medium inlet 101 and flows out from the medium outlet 102. The flow guiding baffle 20 has at least a first state and a second state. When the flow guiding baffle 20 is in the first state, it can follow the flow direction of the cooling medium to make the cooling medium flow stably, so as to cooperate with the heat exchange part for heat exchange to dissipate heat and cool the electronic device attached to the cooling device; when the flow guiding baffle 20 is in the second state, it can reverse the flow direction of the cooling medium, the impact force of the cooling medium on the flow guiding baffle 20 increases, and turbulence of the cooling medium will increase during the flow. By using the directional scouring effect dominated by fluid kinetic energy, it can scour the residues on the inner wall of the medium flow channel, effectively inhibit the deposition of particulate matter, form a self-cleaning dynamic cycle in the medium flow channel, avoid blockage, ensure the heat dissipation effect of the device, and provide a system solution with both anti-blocking ability and heat dissipation stability for high heat flux density scenarios.

[0027] It should be noted that when the diversion baffle 20 is in the first state, that is, the resistance of the diversion baffle 20 to the flow of the cooling medium is small, the diversion baffle 20 mainly plays a guiding role. When the cooling medium flows through, the impact force on the diversion baffle 20 is small. The diversion baffle 20 can reduce the flow rate of the cooling medium, ensure the heat exchange effect between the cooling medium and the heat exchange part, and there is no need to always provide the pumping energy of the cooling medium, thus reducing energy loss; when the diversion baffle 20 is in the second state, that is, the resistance of the diversion baffle 20 to the flow of the cooling medium is large, the impact force of the cooling medium on the diversion baffle 20 is large, and the cleaning of the medium flow channel can be realized.

[0028] Specifically, when the diversion baffle 20 is in the second state, the diversion baffle 20 is in contact with the inner wall of the medium flow channel or there is a gap between them. When the diversion baffle 20 is in contact with the inner wall of the medium flow channel, all the cooling medium forms a turbulent flow along the countercurrent direction, and the purpose of cleaning can be realized. When there is a gap between the diversion baffle 20 and the medium flow channel, a small part of the cooling medium flows through the gap, and most of the cooling medium can still form a turbulent flow along the countercurrent direction to scour the residue in the medium flow channel, and the cleaning effect can also be ensured.

[0029] In specific implementation, the diversion baffle 20 can rotate in any direction relative to the device body. When the diversion baffle 20 is inclined towards the downstream direction of the cooling medium, that is, when the diversion baffle 20 is in the first state, it can be set at multiple angles relative to the device body. Similarly, when the diversion baffle 20 is inclined towards the upstream direction of the cooling medium, that is, when the diversion baffle 20 is in the second state, it can be set at multiple angles relative to the device body. Different angles of the diversion baffle 20 correspond to different cleaning capabilities, and the specific angle of the diversion baffle 20 can be set according to actual needs to ensure that the cooling medium can flow normally in the medium flow channel while achieving the cleaning effect.

[0030] It can be understood that during the switching process between the first state and the second state, the diversion baffle 20 also has a third state perpendicular to the flow direction of the cooling medium. When the cooling medium flows through the diversion baffle 20, a turbulent flow can also be formed, and the cooling device has a certain ability to scour the residues. Specifically, the specific state of the diversion baffle 20 can be adjusted according to actual cleaning needs.

[0031] In some embodiments, a driving mechanism and a rotating shaft 30 driven by the driving mechanism are provided at the top of the device body. The rotating shaft 30 is connected to the diversion baffle 20 and can drive the diversion baffle 20 to rotate to the first state or the second state. Specifically, the rotating shaft 30 can rotate under the drive of the driving mechanism, and the diversion baffle 20 can rotate around the rotating shaft 30 as the rotation center to adjust the angle relative to the medium flow channel, and then switch between the first state and the second state.

[0032] In specific implementation, an installation cavity 121 is formed at the top of the device body. The driving mechanism includes a transmission rack 31 and a transmission gear 32. Both the transmission rack 31 and the transmission gear 32 are arranged in the installation cavity 121, and the transmission rack 31 and the transmission gear 32 are meshed with each other. The transmission gear 32 is fixedly connected to a rotating shaft 30. The rotating shaft 30 is rotatably connected to the installation cavity 121 and extends into the medium flow channel. The transmission rack 31 can move relative to the installation cavity 121 under the action of an external force to drive the transmission gear 32 and the rotating shaft 30 to rotate.

[0033] It can be understood that when the transmission rack 31 moves, the position of the rotating shaft 30 is fixed relative to the installation cavity 121. When the external force moves the transmission rack 31, the transmission rack 31 moves along its extending direction. Through the transmission rack 31, the transmission gear 32 can be driven to rotate around the rotating shaft 30, and then drive the diversion baffle 20 to rotate relative to the medium flow channel.

[0034] Specifically, the installation cavity 121 and the medium flow channel are separated from each other. The cooling medium flows in the medium flow channel and will not enter the installation cavity 121, which can ensure the normal operation of the driving mechanism. A through hole for the rotating shaft 30 to pass through is formed on the wall surface of the installation cavity 121. The rotating shaft 30 is rotationally matched with the through hole, which can not only realize the rotation of the rotating shaft 30, but also realize the sealing between the installation cavity 121 and the medium flow channel when the rotating shaft 30 is inserted into the through hole to isolate the installation cavity 121 and the medium flow channel.

[0035] In some embodiments, a guiding groove 123 is provided on the bottom wall of the installation cavity 121, and a guiding portion is provided on the transmission rack 31. The guiding portion is slidably arranged in the guiding groove 123 to guide the movement of the transmission rack 31. That is to say, the guiding portion and the guiding groove 123 cooperate with each other. Through the guiding groove 123, the movement of the transmission rack 31 can be guided. Specifically, the extending direction of the guiding groove 123 is parallel or coincident with the extending direction of the transmission rack 31, so that the transmission rack 31 moves along its extending direction, thereby driving the transmission gear 32 to rotate.

[0036] Of course, a guiding groove 123 can also be provided on the transmission rack 31, and a guiding portion can be provided on the bottom wall of the installation cavity 121. The present application does not limit this. As long as the guiding groove 123 and the guiding portion can be slidably matched to guide the moving direction of the transmission rack 31, it can be specifically set according to actual needs.

[0037] Refer to Figure 1As shown in the figure, a moving block 33 is provided on the transmission rack 31, and a sliding groove 122 penetrating inside and outside the installation cavity 121 is provided on the device body. The moving block 33 is slidably arranged in the sliding groove 122. It can be understood that the sliding groove 122 penetrates inside and outside the installation cavity 121, and a person's hand can directly push the moving block 33 to move outside the sliding groove 122, so as to drive the transmission rack 31 to move through the moving block 33. That is to say, the sliding groove 122 can provide an operating space for a person's hand, which is convenient for driving the transmission rack 31 to move. The rotating shaft 30 extends into the medium flow channel through the wall surface of the installation cavity 121 away from the sliding groove 122. The rotating shaft 30 is in sealed cooperation with the wall surface of the installation cavity 121 away from the sliding groove 122, which can not only prevent the cooling medium from entering the installation cavity 121, but also prevent dust and other impurities entering the installation cavity 121 through the sliding groove 122 from entering the medium flow channel, ensuring the cleanliness of the medium flow channel. Among them, the sliding groove 122 can also guide the moving block 33 to move, so as to further guide the transmission rack 31 to move and improve the smoothness of its movement.

[0038] Of course, it should be noted that the driving mechanism can also be a driving motor, so as to directly drive the rotating shaft 30 to rotate through the driving motor, without relying on manual operation. Combined with the controller, precise control of the rotating shaft 30 can be realized, so as to precisely adjust the angle of the flow guiding baffle 20. Or, the driving mechanism is other structures, and the present application does not limit this. As long as the rotating shaft 30 can be driven to rotate through the driving mechanism, the flow guiding baffle 20 can be driven to rotate by the rotating shaft 30 to switch to the first state or the second state.

[0039] In some embodiments, referring to Figure 4 As shown in the figure, a number of transmission gears 32 arranged at intervals are engaged on both sides of the transmission rack 31. That is to say, through one transmission rack 31, a number of transmission gears 32 on both sides of the transmission rack 31 can be driven to rotate, so as to be applicable to the flow guiding baffle 20 at different installation positions and drive the flow guiding baffle 20 to adjust its state.

[0040] Specifically, teeth arranged in sequence along the extending direction of the transmission rack 31 are provided on both sides of the transmission rack 31, so as to be engaged with the transmission gears 32 on both sides, and then drive a plurality of transmission gears 32 to rotate by using one transmission rack 31. Correspondingly, power can be transmitted to both sides of the transmission rack 31 corresponding to the transmission gears 32 on both sides.

[0041] In some embodiments, the device body includes a frame body 11, a cover body 12 covering the top of the frame body 11, and a heat exchanger 13 arranged on the bottom of the frame body 11. The frame body 11, the cover body 12 and the heat exchanger 13 jointly enclose a cooling cavity 10, and the heat exchanger 13 forms a heat exchange part. Among them, the frame body 11 can install and support the whole device. The heat exchanger 13 can be a heat-conducting copper plate or other structures with high heat transfer efficiency. The present application does not limit this, and it can be specifically set according to actual needs.

[0042] In specific implementation, the frame body 11 includes four side walls that are connected in sequence. The cover body 12 is disposed on the top of the four side walls, and the heat exchanger 13 is disposed at the bottom of the four side walls. In this way, the frame body 11, the cover body 12, and the heat exchanger 13 can jointly enclose a cooling cavity 10 for accommodating a cooling medium, so that the cooling medium can exchange heat with the electronic device through the heat exchanger 13 to dissipate heat from the electronic device.

[0043] A lapping edge is formed at the bottom of the frame body 11. The heat exchanger 13 is lapped on the side of the lapping edge facing the center of the frame body 11 to be limited on the frame body 11. The inner wall of the lapping edge encloses an opening groove 111, and the heat exchanger 13 is accommodated in the opening groove 111. Further, the heat exchanger 13 is in sealing cooperation with the lapping edge and / or the frame body 11 to ensure the sealing performance of the cooling medium in the medium flow channel.

[0044] Of course, the heat exchanger 13 can also be connected to the frame body 11 in other ways, and this application does not limit this, and it can be assembled according to actual needs.

[0045] An installation cavity 121 is formed on the cover body 12. The driving rack 31 and the driving gear 32 are both disposed in the installation cavity 121 on the cover body 12 to ensure that the heat exchanger 13 at the bottom of the frame body 11 can form a heat exchange part to ensure the stable progress of the heat exchange process.

[0046] Refer to Figure 1 and Figure 3 As shown, a medium partition 40 is provided on the frame body 11, and the medium partition 40 divides the cooling cavity 10 into a medium flow channel.

[0047] Specifically, an opening can be directly formed on the frame body 11 to form a medium outlet 102, or a drain pipe can be installed on the frame, and the drain pipe can serve as the medium outlet 102 to drain liquid through the medium outlet 102; further, an opening can be directly formed on the frame body 11 to form a medium inlet 101, or an opening can be formed on the cover body 12, and the opening is communicated with a liquid inlet pipe to jointly form the medium inlet 101 to introduce the cooling medium into the medium flow channel through the medium inlet 101. This application does not limit this, and it can be specifically set according to actual needs.

[0048] Of course, the medium inlet 101 and the medium outlet 102 can also be other structural forms, and this application does not limit this, as long as the cooling medium enters the medium flow channel from the medium inlet 101 and flows out from the medium outlet 102 to take away the heat from the heat exchange part from the electronic device to be cooled.

[0049] In some embodiments, the frame body 11 includes a first side wall and a second side wall oppositely arranged along a first direction. The number of the dielectric partitions 40 is at least two, and the at least two dielectric partitions 40 are spaced along a second direction. Among two adjacent dielectric partitions 40, one is connected to the first side wall and is spaced from the second side wall, and the other is connected to the second side wall and is spaced from the first side wall, wherein the first direction intersects the second direction.

[0050] That is to say, the at least two dielectric partitions 40 are spaced along the second direction. Among two adjacent dielectric partitions 40, one is in contact with and connected to the first side wall, and a gap is formed between the second side wall along the first direction. The other is in contact with and connected to the second side wall, and a gap is formed between the first side wall along the first direction.

[0051] Specifically, the first direction is perpendicular to the second direction. The frame body 11 further includes a third side wall and a fourth side wall oppositely arranged along the second direction. The third side wall, the fourth side wall, and the at least two dielectric partitions 40 are parallel and spaced from each other. The dielectric partition 40 is perpendicular to the first side wall and the dielectric partition 40 is perpendicular to the third side wall.

[0052] The at least two dielectric partitions 40 divide the cooling cavity 10 into a plurality of dielectric flow channels. That is, between adjacent dielectric partitions 40, between the dielectric partition 40 and the third side wall, and between the dielectric partition 40 and the fourth side wall, dielectric flow channels can be formed. The diversion baffle 20 is disposed in at least one dielectric flow channel.

[0053] The plurality of dielectric flow channels flow in sequence to jointly form a dielectric flow channel. It can be understood that between adjacent dielectric flow channels, they can flow through the gap between the dielectric partition 40 and the second side wall along the first direction, or can flow through the gap between the dielectric partition 40 and the first side wall along the first direction, so as to realize the full connection of the plurality of dielectric flow channels, so as to realize the flow of the dielectric in the cooling cavity 10 through a dielectric inlet 101 and a dielectric outlet 102.

[0054] Exemplarily, the number of the dielectric partitions 40 is two. The two dielectric partitions 40 are spaced along the second direction and can divide the cooling cavity 10 into three dielectric flow channels. The three dielectric flow channels are arranged in sequence along the second direction. And one of the two dielectric partitions 40 is connected to the first side wall. The dielectric flow channels on both sides of the dielectric partition 40 flow through the gap between the dielectric partition 40 and the second side wall along the first direction. The other is connected to the second side wall. The dielectric flow channels on both sides of the dielectric partition 40 flow through the gap between the dielectric partition 40 and the first side wall along the first direction. In this way, the sequential flow of the three dielectric flow channels can be realized.

[0055] Of course, it should be noted that the number of the medium partitions 40 can also be three, four or more. This application does not limit this as long as they are arranged at intervals in the second direction, and among any two adjacent medium partitions 40, one is connected to the first side wall and is spaced from the second side wall, and the other is connected to the second side wall and is spaced from the first side wall.

[0056] In some embodiments, there are two sets of the diversion baffles 20 located in the same medium diversion channel, and the states of the two sets of diversion baffles 20 are the same.

[0057] Specifically, referring to Figure 3 As shown, the three medium diversion channels include a first medium diversion channel 103. A first medium diversion channel 103 is formed between one of the two medium partitions 40 and a side wall (i.e., the third side wall) of the frame body 11 in the second direction. The two sets of diversion baffles 20 are respectively arranged on the side walls opposite to the third side wall and the medium partition 40, and the operating states of the two sets of diversion baffles 20 are the same. Moreover, the tops of the two sets of diversion baffles 20 in the first medium diversion channel 103 are in contact with the cover body 12, the bottoms are in contact with the heat exchanger 13, and one of the two sets of diversion baffles 20 is in contact with the medium partition 40, and the other is in contact with the third side wall. The two sets of diversion baffles 20 are separated from each other. Thus, the cooling medium can only flow through the diversion baffles 20 in the first medium diversion channel 103.

[0058] The three medium diversion channels further include a second medium diversion channel 104. A second medium diversion channel 104 is formed between the two medium partitions 40. The two sets of diversion baffles 20 are respectively arranged on the side walls opposite to the two medium partitions 40, and the operating states of the two sets of diversion baffles 20 are the same. Moreover, the tops of the two sets of diversion baffles 20 in the second medium diversion channel 104 are in contact with the cover body 12, the bottoms are in contact with the heat exchanger 13, and one of the two sets of diversion baffles 20 is in contact with one of the medium partitions 40, and the other is in contact with the other medium partition 40. The two sets of diversion baffles 20 are separated from each other. Thus, the cooling medium can only flow through the diversion baffles 20 in the second medium diversion channel 104.

[0059] The three medium diversion channels further include a third medium diversion channel 105. Another one of the two medium partitions 40 and the other side wall (i.e., the fourth side wall) of the frame body 11 along the second direction form the third medium diversion channel 105. Two groups of diversion baffles 20 are respectively arranged on the opposite side walls of the fourth side wall and the medium partition 40, and the working states of the two groups of diversion baffles 20 are the same. Moreover, the tops of the two groups of diversion baffles 20 in the third medium diversion channel 105 are in contact with the cover body 12, and the bottoms are in contact with the heat exchanger 13. One of the two groups of diversion baffles 20 is in contact with the medium partition 40, and the other group is in contact with the fourth side wall. The two groups of diversion baffles 20 are separated from each other. In this way, the cooling medium can only flow through the diversion baffles 20 in the third medium diversion channel 105.

[0060] Among them, the end of the first medium diversion channel 103 far from the second medium diversion channel 104 and the end of the third medium diversion channel 105 far from the second medium diversion channel 104 can respectively form a medium inlet 101 and a medium outlet 102, so that the cooling medium flows through the first medium diversion channel 103, the second medium diversion channel 104 and the third medium diversion channel 105 in sequence, thereby realizing heat dissipation and cooling.

[0061] It should be noted that when using the cooling device for heat exchange and cooling of electronic equipment, the working states of the diversion baffles 20 in multiple medium diversion channels are the same and in the first state; when cleaning the medium flow channels inside the cooling device, the working states of the diversion baffles 20 in multiple medium diversion channels are the same and in the second state.

[0062] Specifically, each of the three medium diversion channels is provided with a driving rack 31. The number of the rotating shafts 30 is adapted to the number of the diversion baffles 20. In this way, the occupied space of the driving mechanism can be saved, and the state switching efficiency of the diversion baffles 20 can be improved. Specifically, the driving rack 31 can drive multiple driving gears 32 to rotate simultaneously to adjust the two groups of diversion baffles 20 in the same medium diversion channel at the same time, that is, the driving gears 32 on both sides of the driving rack 31 respectively control the two groups of diversion baffles 20 to adjust their states.

[0063] Exemplarily, three driving gears 32 are arranged on both sides of each driving rack 31. Corresponding to the three driving gears 32, three rotating shafts 30 are provided to respectively connect the three diversion baffles 20 in a one-to-one correspondence, that is, the number of the diversion baffles 20 in one group is three. By moving one driving rack 31, the state adjustment of the diversion baffles 20 on both sides can be realized simultaneously.

[0064] Specifically, a first mounting hole 112 is formed in the frame body 11, and a second mounting hole 124 is formed in the cover body 12. The cover body 12 is fixedly connected to the frame body 11 through fasteners such as screws passing through the second mounting hole 124 and the first mounting hole 112, so as to fix the diversion baffle 20 inside the medium flow channel. Specifically, the second mounting hole 124 can be directly formed as a threaded hole, so as to directly complete the installation of the cover body 12 on the top of the frame body 11 during the tightening process of the fasteners.

[0065] Of course, the frame body 11 and the cover body 12 can also be connected in other ways, which is not limited in this application and can be specifically set according to actual needs.

[0066] In some embodiments, referring to Figure 1 As shown, a sealing gasket 14 is provided between the frame body 11 and the cover body 12. It can be understood that through the setting of the sealing gasket 14, the sealing between the frame body 11 and the cover body 12 can be realized, and then the sealing of the medium flow channel can be realized, so that the cooling medium can only enter from the medium inlet 101 and flow out from the medium outlet 102. The sealing gasket 14 can be an elastic member such as a rubber gasket or a silicone gasket, so as to deform under the pressing effect between the frame body 11 and the cover body 12 to fill the gap between the frame body 11 and the cover body 12, and then the sealing between the frame body 11 and the cover body 12 can be completed.

[0067] Specifically, a third mounting hole is formed in the sealing gasket 14, and the first mounting hole 112, the second mounting hole 124, and the third mounting hole are correspondingly arranged, so that the fasteners can pass through the third mounting hole at the same time to complete the limiting and fixing of the sealing gasket 14 between the cover body 12 and the frame body 11.

[0068] Specifically, the number of the first mounting hole 112, the second mounting hole 124, the third mounting hole, and the fasteners is multiple, and they are correspondingly arranged one by one.

[0069] In some embodiments, continuing to refer to Figure 1 As shown, a plurality of clamping frames 15 are arranged at intervals along the circumferential edge of the top of the frame body 11, and a plurality of corners of the cover body 12 are correspondingly clamped in the plurality of clamping frames 15. It can be understood that the clamping frames 15 can realize the pre-positioning of the cover body 12 relative to the frame body 11 during the installation of the cover body 12, and reduce the installation difficulty. Specifically, when a plurality of corners of the cover body 12 are correspondingly clamped in the plurality of clamping frames 15, the first mounting hole 112 on the frame body 11 and the second mounting hole 124 on the cover body 12 can correspond one by one, so as to facilitate the positioning and tightening of the fasteners and reduce the installation difficulty.

[0070] Specifically, the clamping frame 15 is formed into an L-shaped structure to adapt to the shape of the corner of the cover body 12 and complete the positioning and limiting of the cover body 12.

[0071] Refer to Figure 1 As shown, the cover body 12 is formed into a square structure with four corner positions. The number of the clamping frames 15 is four, and the four clamping frames 15 correspond to the four corners of the cover body 12 one by one.

[0072] Specifically, avoidance grooves may be formed at multiple corners of the cover body 12. The clamping frames 15 are limited in the avoidance grooves, which can prevent the clamping frames 15 from protruding from the surface of the frame body 11 and ensure the flatness of the outer surface of the device body. Further, avoidance portions are also formed on the sealing gasket 14 for accommodating the clamping frames 15.
